About this app

CementMix is the construction materials calculator built for people who actually work on site.
Enter the volume or the area of your job and instantly get the exact quantities of cement, sand, gravel, lime and water your mix needs. No guesswork, no waste: reliable figures based on real technical proportions.
■ WHO IT IS FOR
Bricklayers, surveyors, building contractors, tilers and DIY enthusiasts who want to order the right amount of material and avoid leftovers or extra trips.
■ HOW IT WORKS
Pick the product, enter the size of the job (volume in m³, or thickness and surface area) and CementMix does the rest. Every result tells you how many bags you need, how much aggregate and how much mixing water.
■ AVAILABLE CATEGORIES

- Floors — screeds, subfloors, pervious concrete and other flooring solutions
